Step 4: Machine that Wax!
Out of the mold, the wax will have a HUGE sink mark in the middle; I usually just clamp the sides of the block and face off about ¼” to get it flat. Then I flip the block and machine to thickness. If you are carful and clean your vacuum ahead of time, you can save the chips to re-melt later. I keep a container nearby where I store my wax chips.
Recycle Your Wax
When recycling your wax, I recommend using no more than 50%-75% reground wax. This is due to the fact that plastics degrade rapidly when heated (think compost) and can start to smoke/burn/ignite if you are not careful. Therefore, start by melting paraffin wax, adding new bags and THEN adding your recycled wax.
Good luck and be safe!
